DOOR-CHECK.

SPECIFECATION forming part 0f .Letters lftent No. 684,586, dated October15, 1901. application filed October 16, 1900. Serial No. 33,275- (NO11101181) To r/,ZZ whom it' may concern,.-

Be it known that We, JOHN F. NEHER, rcsiding at Saginaw, in the countyof Tarrant and State of Texas, and NOAH N. NEHER, residing at Stockton,in the county of Rooks and State of Kansas, citizens of the UnitedStates, have invented new and useful Improvements in Door-Ohecks, ofwhich the following is a specification.

This invention relates to new and useful improvements in door-checks;and its primary object is to provide a device of simple and durableconstruction adapted to be secured to a door of any form and which willeffectively hold the door in any position to which it may be swung.

A further object is to provide means where* by said check may be readilyreleased from contact'with the iioor.

The invention consists in the novel construction and combination ofparts hereinafter more fully described and claimed, and illustrated inthe accompanying drawings, showing the preferred form of my invention,and in which- Figure 1 is a vertical section through the door-check,showing the same in position upon a door. Fig. 2 is a front elevationthereof; and Fig. 3 is a section on line 3 3, Fig. 1.

Referring to said iigures by numerals of reference, 1 is a substantiallysemicylindrical casing having a tongue or plate 2 extending from one endthereof and adapted to be secured to a door in any suitable manner. Ears3 extend from the opposite end of the casing and are also adapted to besecured to a door. A tube 4 is slidably mounted within the lower end ofthe casing, and a plug 5, of rubber or other suitable material, isiitted within the bottom of this tube and is adapted to be forced intocontact with the Hoor. An annular flange G is provided at the upper endof the tube 4, and a coil-spring 7 incloses the tube7 the ends thereofbearing upon the iiange 6 and upon the bottom of the casing 1. Thisspring serves to hold the tube 4 and the plug therein normally raised. Apartition 8 is formed within the tube 4, and slidably mounted therein isa plunger 9, which eX- tends upward through the top of the tube 4 andthe casing 1. A sleeve 10 is secured upon the plunger at a pointadjacent to the upper end of the tube andis slidably mounted within saidtube. A coil-spriug 11 incloses the plunger and bears at opposite endsupon said sleeve and the partition 3, respectively. This spring servesto hold the plunger normally projected from the top of the tube 4. Agroove 11n is formed within a wali of the aperture in the partition Sand is adapted to serve as a guide fora stud 12, formed at the lower endof the plunger 9. This stud serves to prevent the plunger from turningwithin the tube. The upper portion of the plunger 9 is squared, as at12a, and the upper end of this squared portion is provided with afootplate 13, whereby said plunger maybe readily depressed by placingthe foot thereon. Teeth 14 are formed upon the inner surface of thesquared portion 12 and are adapted to be engaged by a dog 15, extendingdownward from a plate 1G, having a tongue l7extending within an aperture18, formed within the tongue 2 at a point adjacent to the top of thecasing 1. This plate incloses the plunger, and' a spring 19 serves tohold the dog thereof normally in engagement with one of the teeth 14.-.

Vhen it is desired to hold the door in a cer` tain position, the plunger9 is depressed, resulting in the contraction of the springs 7 and 1l.The tube 4 will be carried downward until the plug 5 contacts with theiioor. During the downward movement of the plunger the dog l5 will slipover the teeth 14, and as soon as the movement of the plunger hasstopped said dog will engage one of the teeth and hold the plunger inthe position to which it was forced. When it is desired to release thestop from engagement with the Hoor, it is merely necessary to depressthe plate 16. This will cause the dog 15 to swing back out of engagementwith the tooth,and the plunger 9 and the tube 4 will then be free tospring upward to their normal positions.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is

1. The combination with a casing, of a flanged tube slidably mounted inthe lower end thereof, a spring inclosing said tube bearing at one endagainst the flange thereof and adapted to hold the saine normallyretracted,

a partition within the tube, a plunger slidably mounted Within thepartition and extending through the upper end of the easing. a springWithin the tube and inolosing the plunger and adapted to hold the samenormally projected upward from the tube, teeth upon the plunger, a plateinelosing said plunger and hinged to the casing, a dog to said plateadapted to engage the teeth, and means for holding said dog normally inengagement therewith.

2; The combination with a casing, of a tube slidably mounted in thelower end thereof, a plug within the bottom of the tube, a springinclosing said tube and adapted to hold the Same normally retracted, apartition within thetube, a plunger slidabl'y mounted therein, a studthereon slidably mounted Within the partition, a sleeve upon the plungerand Within the tube, a spring inelosing the plunger and zo bearing atopposite ends upon the partition and sleeve, teeth upon the plunger, afootplate upon said plunger, a plate hinged to the easing and inelosngthe plunger,a dog thereto adapted to engage one of the teeth, and aspring holding said dog normally in Contact with the teeth.

In testimony whereof We alix our signatures in presence of tWoWitnesses.
